Blackt Electrotech : BT31W PIR Sensor Motion Sensor Energy Saving Motion Detector Wall Mounted

Good work nice

Working till now for 2 months

Works fine. Initially received a faulty one, so claimed for replacement. Amazon did a hassle free replacement & collected back the faulty one, thanks to Amazon. Wiring and installation was also easy. Avoids human involvement for turning on & off the lights. Works fine so far, have to wait to see it's lifetime.

Sensor has not a wide angle. It works only when someone is moving infront of this. The wide angle is less than 30 degrees. Sensor doesn't work if kept over 4 meters range. I have installed it in my gallery of 10 meters but it only works when you are at a distance of around 4 metres or less. Motion sensing is slow. If you run infront of it, it doesn't work. The lights are on after a delay of 2 seconds.

Don’t ever buy this product try to get different brand with warranty in case any issue so you can return. The company claim sensor range is 12meter but it’s not even working for 3meter. I bought two only used one and got bad result and tried to return second one but company is saying no return. Avoid buying this brand.

Good product.

Good product, works as desired. Works as indicated with both light sensor and the timer feature

Good working

So far it is working fine as expected
